Toss the shrimp in baja/mexican/taco seasoning. You can cook them outside on the grill (you may want to skewer them to make it easier) or inside in a grill pan or in a skillet. Cook shrimp on high for 1 minute on each side. Set aside in a serving bowl.

To prepare the tortillas, wrap them (all together) in a damp kitchen towel and place them in a warm oven on a baking sheet for 5-8 minutes or microwave for 1 minute.

To make the assembling easy for your guests, I like to put all of the toppings on one platter. It makes a very easy clean up - only one platter to wash vs. individual bowls for each topping.
